The gravitino in gaugino mediation
- 1. Deutsches Elektronen-Synchrotron DESY, 22603 Hamburg (Germany)
Description
We show that for gaugino mediated supersymmetry breaking the gravitino mass is bounded from below. For a size of the compact dimensions of order the unification scale and a cutoff given by the higher-dimensional Planck mass, we find m3/2-bar 10 GeV. In a large domain of parameter space, the gravitino is the lightest superparticle with a scalar τ-bar -lepton as the next-to-lightest superparticle
